Szukana fraza: [Abstract = "This paper presents a concept of designing fault tolerant control systems with the use of suboptimal methods. We assume that a given \(nonlinear\) dynamical process is described in a state space. The method consists in searching \(at the off\-line stage\) for a trajectory of operational points of the system state space. The sought trajectory can be constrained by certain conditions, which can express faults or failures already detected."]
